The soldier will be able to identify the elements of fundamentals of transmission, reception, radio wave
and methods of transmission.
Given information and diagrams about the elements of fundamentals of transmission and reception,
radio wave and methods of transmission.
Demonstrate competency of the objective by responding to 85 percent of the multiple-choice test
covering the elements of fundamentals of transmission, reception, radio wave and methods of
transmission for lesson 1.
FM 11-65, FM 24-18, and FM 24-21.

ELEMENTS OF TRANSMISSION AND RECEPTION
(RF) energy; a source of electrical power; a key, microphone, or teletypewriter, that controls these
energy waves; a transmitting antenna that radiates RF waves; a receiving antenna that intercepts some of
the radiated RF waves; a source of electrical power; a receiver that converts intercepted RF waves into
usable energy (usually audio frequency (AF) energy); and a loudspeaker, headphones, or teletypewriter
provided intelligibility. When the frequency coverage of two sets is similar, when they have the same
modulation, and the distance between them does not exceed the range of the equipment, two-way
communications using electromagnetic (radio) waves is possible. Figure 1 is a block diagram of a basic
